Customer Success & Implementation Manager

About Weissr

Weissr is building the next-generation Capex platform, fundamentally changing how capital-intensive enterprises plan, prioritise and allocate their investments. Our approach is not theoretical, it is proven in practice and described in the book Redesigning Capex Strategy, written by our founders and based on more than two decades of hands-on experience.

Today, Weissr is used by large enterprise customers across Europe and North America, with users in more than 70 countries. Our customers include global leaders in capital-intensive industries such as energy, chemicals and manufacturing.

Backed by our new majority owner Monterro, we are entering our most ambitious growth phase to date, with a clear objective to scale recurring revenue 5x. This requires focus, pace and strong customer partnerships that drive successful implementations, high adoption and long-term ARR growth.

Our culture is built around the idea that everyone is an entrepreneur. This means taking ownership, putting customers first, being open about both successes and setbacks, acting with speed, and building trust across the team.

The Role

This is an opportunity to take on an influential role at the intersection of customers, technology and business. You will work closely with some of the world's leading capital-intensive companies and play an important role in both their success with Weissr and our continued growth.

We are looking for a person with a technical background to help ensure customers derive maximum value and satisfaction from our solutions.

You will work across the entire customer lifecycle, from leading implementation projects through configuration, onboarding and training, to proactively identifying and addressing the needs of existing customers and providing ongoing customer support. This is a broad and varied role where your day-to-day work will differ depending on customer and business needs, with the overall goal of building long-term relationships and delivering measurable business impact.

The role requires a strong business mindset combined with technical interest and understanding, as well as the ability to understand customer challenges and translate them into effective solutions.

Key Responsibilities

In this role, you will:

• Lead implementation projects, including planning, configuration of our Capex software solution, onboarding and hands-on training.
• Build strong relationships with key external stakeholders such as CFOs, Heads of Capex, Controllers and operational leaders.
• Identify opportunities for expansion, upselling and cross-selling.
• Drive structured post-go-live adoption plans and organisational rollout.
• Provide ongoing support through troubleshooting and proactive communication.
• Lead renewal processes and proactively manage commercial dialogue.

Your Background

You likely have:

• Several years of experience in Customer Success, technical support, Management Consulting and/or complex B2B SaaS environments or similar
• Experience leading customer implementations or structured client projects
• Proven ability to manage enterprise stakeholders and long-term customer relationships, to drive renewals and expansion
• Experience leveraging AI technologies and tools
• Experience with databases and writing basic SQL queries
• Comfort working in Microsoft Office, especially Excel, with the ability to analyse and structure data
• Experience working with CRM, customer success and project management tools, such as HubSpot and Jira
• Fluent in both written and spoken English and Swedish

It is considered a strong plus if you have experience working with capital-intensive industries, engaging with finance, controlling or investment functions, and have a solid understanding of financial terminology and processes.

Who You Are

You take ownership beyond delivery and proactively look for ways to deepen customer engagement and increase the value customers get from our SaaS platform.

You are comfortable balancing executive conversations with hands-on implementation leadership.

You are a structured and analytical thinker who easily spots patterns and breaks down complex challenges into clear, actionable steps.

You have a high technical interest and understanding.

You are comfortable stepping in and taking ownership beyond your core focus when needed.

Working at Weissr

At Weissr, you will have the opportunity to influence more than your own role. We are a small team with global customers and ambitious growth plans, which means good ideas can quickly turn into action and individual contributions genuinely matter.

You will join a highly ambitious, collaborative and down-to-earth team with its base in Gothenburg and a global footprint. Weissr combines deep domain expertise with modern SaaS and is shaping a new category within Capex Strategy & Management.

The position is based at our Gothenburg office.
